host packages.zonalivre.org
packages.zonalivre.org is an alias for packages.zonalivre.org.s3.amazonaws.com.
packages.zonalivre.org.s3.amazonaws.com is an alias for s3-directional-w.amazonaws.com.
s3-directional-w.amazonaws.com is an alias for s3-1-w.amazonaws.com.
s3-1-w.amazonaws.com has address 54.231.1.137
